Definitions

  • the invention relates to the general technical field of systems ensuring the operational safety of the engines of an aircraft, and in particular the operational safety of a turbine engine of a rotorcraft.
  • the second engine can not be stopped in case of overspeed. Such a situation is unlikely but possible. Consequently, if the second engine is subsequently under overspeed condition, this second engine can not be stopped automatically since its protection is inhibited. The second engine may therefore be in an overspeed situation.
  • At least one engine comprising a valve on a fuel line, the engine is automatically shut off by closing the valve.
  • Each speed sensor comprises for example an electromagnetic sensor placed in front of a sound wheel rotating in rotation with the rotary member whose speed of rotation is to be measured.
  • This power turbine can be linked to the gas generator.
  • the power turbine is a free turbine independent of this gas generator according to the figure 1 .
  • the rotorcraft is further provided with an overspeed safety system 20 to prevent engine overspeed 10.
  • the processing unit may comprise a logic circuit or the like.
  • This torque measuring system 35 is arranged on the power unit to measure the torque Tq exerted on the power unit 19.
